#118349 slyguy (User) What happens in the garage stays in the garage. Platinum Boarder Posts: 1869 Does a change of pipes require rejetting 3 Years, 8 Months ago   I have the kury hypercharger & HK 3" big straights, along with a Dynojet jet kit. Was thinking of changing my pipes out to Freedom true duals. Would I need to rejet if I did this?   Logged     2004 Road Star Silverado (original owner), over 55K mostly trouble-free miles Patriot Guard Rider, IBA Member, Star Touring & Riding   The administrator has disabled public write access. #118351 DocShadow (Admin) Hmmmm .... send beer Admin Posts: 17615 Re:Does a change of pipes require rejetting 3 Years, 8 Months ago   Not major rejetting, unless it is already badly jetted, but you may have to 'tweak' it a bit.

Platinum Boarder Posts: 1869 Re:Does a change of pipes require rejetting 3 Years, 8 Months ago   I didn't mess with it. I had a shop do it. They screwed it up (and have since gone out of business) and it was running way too rich. I had another shop redo it and it is now right. I get good gas mileage, about 43-45MPG, have no back firing and plugs last a long time. When and if I do it; I will do the jetting my self this time, but since I never did this before I will definetly need help and lots of it. I've gotten more courageous with doing things thanks to this site.   Logged     Last Edit: 2008/09/10 15:02 By slyguy.   2004 Road Star Silverado (original owner), over 55K mostly trouble-free miles Patriot Guard Rider, IBA Member, Star Touring & Riding   The administrator has disabled public write access. #118374 Jason19 (User) Yes, I am a Pirate, 200 years too late Senior Boarder Posts: 267 Re:Does a change of pipes require rejetting 3 Years, 8 Months ago   6 weeks ago, I had never been into a carb, always had FI...and now, I could probably do it in the dark And thanks to Doc, I think I even got it pretty close to right! You will be fine, just be patient and have a good clean work area...and don't forget the little spring that goes over the needle.   Logged     -Jason   The administrator has disabled public write access. #118381 russdustus (User) Junior Boarder Posts: 162 Re:Does a change of pipes require rejetting 3 Years, 8 Months ago   I would say to put the pipe on and see how she runs. If it starts to pop a little on decel or won't rev when you give it throttle, I'd say you would be a little lean and you should start with the pilot jet. However, most pipe changes don't do anything for AIR/FUEL intake ratio, so you shouldn't have to rejet just because you change the pipes. They let air out, not in. Sure, they change the back pressure. But does it effect the carboration? I think not. Just my thoughts.

As I posted .... if it's jetted correctly you may/may not have tweak it, but it you do it's not a major rejet such as when you change out the pipes and airbox.

I have the B.A.K. and V&H LS pipes. The Baron jet kit I used, have suggested main jets for stock, aftermarket baffle and aftermarket no baffle pipes. But unless the intake is changed exhaust should'nt require re-jet.   Logged     Motorcycles are only truely happy when they are goin fast.   The administrator has disabled public write access.
